A Novel Active Switched-Inductor Based Hybrid Boost-Cuk Converter with High Voltage Gain

Abstract

This paper presents a novel transformer less high gain DC-DC converter based on active switched inductor. The proposed converter features high voltage gain with reduced voltage stress across the power switch compared to the state-of-the-art converter topologies with same component count. The continuous input current of the converter facilitates suitable interface of a low voltage solar PV source to DC or AC grid having higher voltage level. Moreover, due to its bidirectional feature, the proposed converter is capable of interfacing battery or ultracapacitor to the traction inverter in an EV drive train. This paper illustrates operating principle and steady-state analysis of the proposed converter. Dynamic modelling and controller design have been discussed to regulate input current and output voltage of the converter. To validate the efficacy of the proposed converter, closed-loop simulation results has been presented. © 2023 IEEE.
